Pool Safety Net Overview
Custom-fit, removable safety netting designed for residential pool safety. The net anchors into the deck around the pool perimeter and is tensioned above the water to help prevent unsupervised access while keeping the pool visible. Tested to ASTM F1346 when properly installed.
Product Overview
All-Safe Safety Nets are cut and fitted on site from 5mm high-density virgin polyethylene netting, machine-tied into 3½-inch squares. On most installs, stainless steel clips along the net’s edge attach to anchors set into the deck, and a central tensioning system (CTS) pulls the net up off the water. A net only does its job anchored and tensioned.
How the homeowner uses it. To open the pool they release the tension on the CTS, walk the perimeter unhooking the clips, and roll the net up on the storage roller. Putting it back on reverses that — clip the perimeter, then tighten the CTS to lift the net clear of the water.
Set the expectation while you quote. Nets sit low and nearly disappear against the water, so they suit customers protecting a view who don’t want a fence up. The trade-off is time: the net has to come fully off to use the pool and go fully back on afterward. It is not as quick or as convenient as a removable fence, and a customer who understands that up front is a happy customer.

How to Calculate What to Order
Net orders are built from the pool’s dimensions, the deck surface, and the tensioning layout. Work through these steps before ordering so the net width, anchor count and CTS components match the pool.
Completing these steps first helps ensure accurate quantities, proper component selection, and a smoother installation.
When you are ready to place your order, you can do so via the Shop Page or Net Quick Order Page
Step 1: Qualify the Pool
Not every pool qualifies for a net. Confirm fit before you quote:
- Water clearance — the gap between the water surface and the underside of the tensioned net. The minimum rises with net size: 4” up to 20 ft, 5” to 30 ft, 6” to 40 ft, 7” beyond that (see the Net Chart). Infinity, zero-edge, beach-entry and rim-flow pools are a call to the office before you quote — they need a case-by-case decision, not a yes or no from this page.
- Pool size — not recommended over 50 ft in either length or width.
- Water contact and wicking — anywhere the net will touch the pool water (waterfalls, water features, spillways, an infinity edge), the water travels along the netting. If the net slopes from a high point to a low point, it carries that water to the anchors — and anchors set on top of or above the coping will dump it outside the pool, which can add up to real water loss. Plan anchor placement so the water drains back in. Water Runoff Due to Wicking
- Obstructions — ladders, handrails, slides, diving boards, rock formations, water features and spillways all need a plan.
- The customer — who will apply and remove the net, and do they need to pass an inspection?
Watch for lockoff. A round pool tensions evenly, because the CTS sits the same distance from every edge. The less regular the shape — a spa off to one side or in the middle, an L-shape, a raised spa — the more the CTS-to-coping distance varies, and some areas end up where the CTS simply cannot release and apply tension. That is lockoff.
Catch it before you quote. There are two ways to handle it, and both cost far less now than after the anchors are in:
- Threaded brass anchors with round loop clips in the lockoff area, applied and removed with the Round Loop Tool & Allen key. It adds cost, but most customers prefer it — the spa or lockoff area can be reached without releasing tension on the whole net.
- Deck overlap — add material so the net overlaps the deck in those areas, evening out the distance to the coping so the CTS tensions properly. Cheaper, but less tidy visually, since the net no longer follows the pool shape.
Not every pool has lockoff. But if you leave it unaddressed, expect a callback about slack in those areas — and the fix then means drilling out anchors you already set. Pool Shape: Lockoff & Deck Overlap
Review: Not All Pools Qualify · Water Clearance · Is this Customer a Good Candidate? · Elevation Changes, Steps & Columns
Step 2: Measure & Choose Net Width
Raw nets start as rectangles. Find the smallest rectangle that covers the entire pool (and spa, if one net will cover both), including swim-outs and sun shelves, measuring from where the furthest anchor will sit – behind the coping, on the coping, or on the face of the coping.
- Add for the CTS: add 3 ft to both the length and the width so there is material for the central tensioning system; add another foot each way if the net will have more than one CTS
- Add for height: anything the net has to climb – retaining walls, raised spas, steps, columns, waterfalls – needs more net. Add 1 ft of length and width for every 4 ft of vertical rise
- Always round up to the next full foot (32.5 ft becomes 33 ft)
- Pick the material width that clears the final width: 12, 24, 34 or 50 ft, and order the final length
- Walk and record the full perimeter – you need it for the anchor count
Example: a 20 × 31 pool with one CTS and no walls needs at least 23 × 34, so order 24-ft-wide material × 34 ft.
Review: Determining Net Size · Net Material
Step 3: Count Anchors & Clips
Anchor spacing is set by the anchor and surface type, not by the size of the pool. Nearly everything runs at 24”; wall attachment is the exception.
- 24” between anchors — keyhole in concrete, keyhole in paver/brick/stone, threaded keyhole in concrete, threaded keyhole in paver/brick/stone, composite, wood-deck threaded, and existing anchors. These all sit 12” or more from the waterline.
- 12” between anchors — wall attachment in concrete, paver, brick, stone or tile, and steel bar. These sit 0–6” from the waterline, so they take roughly twice as many anchors per foot.
To count them: anchor perimeter in feet ÷ (spacing ÷ 12). At 24” that works out to perimeter ÷ 2 — a 120 ft perimeter is about 60 anchors. At 12” it is one anchor per foot.
Measure the anchor perimeter off your anchor-to-anchor rectangle, not the pool edge, and count each surface separately if the job uses more than one anchor type. Chalk the deck to confirm before ordering.
Clips: one per anchor, matched to the anchor. Use extended cone head clips (2”, 4”, 6”) at raised walls and elevation changes. Clips come in bags of 10; carabiners in bags of 5.
Step 4: Choose the Anchor Type
Anchor type follows the surface the anchor bites into – and switching mid-install is expensive.
- Concrete deck behind the coping: brass keyhole anchor (0.730 / 0.740 / 0.750), ¾” core bit
- Pavers, stone and softer decks: composite anchor (Gray, Putty, Red, White) or anchor pipe
- Wood decks: threaded wood-deck anchor
- Walls and raised bond beams: wall attachment kit, or pad-eye anchors with carabiner clips and nail-in anchors
- Threaded brass anchors with round loop clips where the net locks off and won’t pull tight (pool shape, spa location), and for no-CTS installs; pear loop clips fit existing winter-cover anchors
Which keyhole size? It follows the wear on your ¾” net core bit: start a new bit with 0.750 anchors, move to 0.740 as it wears, then 0.730. Keep all three on hand – you can’t predict how fast a bit wears.
Review: Deck Surface · Standard Brass Anchor · Composite Anchor
Step 5: Choose the CTS Layout & Tensioning Device
The Net Chart picks the tension system for you. Take your anchor-to-anchor measurement and look at the larger of the two dimensions:
- Up to 12 ft — Loop Tool, no CTS. 4” minimum water clearance. Net bag for the smallest; roller once the other dimension passes about 16 ft.
- 13–20 ft — 10 Mesh CTS, 4” minimum clearance, roller
- 21–30 ft — 12 Mesh CTS, 5” minimum clearance, roller
- 31–40 ft — 14 Mesh CTS, 6” minimum clearance, roller
- 41–50 ft — Double 12 Mesh CTS, 7” minimum clearance. A roller may not work at this size.
Worked examples: 26’ × 38’ calls for a 14 Mesh CTS. 31’ × 42’ calls for a Double 12 Mesh. The chart is a guideline — odd shapes and elevation changes get evaluated case by case, so call the office if the job is unusual.
The central tensioning system (CTS) is ordered as its own set of components in the net color, and you choose who installs it.
- CTS layout: Single, Single Offset, Double or Double Offset – driven by pool shape and where the homeowner will stand to tension
- Add pulleys, pulley string and CTS pull cord in the net color
- Want All-Safe to install the CTS for you? Add “CTS Installation” to the order (labor only – you still order the pulleys, pulley string and CTS cord). We tie the pulleys in place in the center of the net material. Any Offset or Double Offset CTS requires the custom CTS order form showing where each CTS goes on the net: Custom CTS Order Attachment (PDF) · see a completed example. CTS Installation is an additional fee and adds 1–2 days of order processing time.
- No-CTS option for small nets: nets under about 12 ft wide (spas, ponds, fountains, lap pools and small pools) can skip the CTS. Make at least half the anchors threaded brass, grouped together on one side, with a round loop clip on each, and tension with the Round Loop Tool & Allen key. Still ASTM-compliant (it uses a removable tensioning tool) and usually cheaper. How to install a net with no CTS (PDF)
- Tensioning device: Titan Tool small or large by pool size, Ratchet Assembly, or Round Loop Tool & Allen key for narrow lap pools and spas

Step 6: Review & Verify Before Ordering
Before submitting an order, confirm:
- Net width clears the widest point of the pool and spa
- Anchor and clip counts match your chalked spacing
- Anchor type matches the deck surface
- All CTS parts, twine and cord are the same color as the net
- Perimeter wrap twine, net & warning label, and any roller or storage bag are on the order
- Tools on hand: ¾” core bit, key hole tamping tool, heat cutter
Use the Net Attachment form to draw the layout with your customer before you order.
Important Planning Notes
All-Safe products are sold à la carte. Net material, anchors, clips, CTS components and tensioning devices are each ordered separately – there are no complete “net kits”.
If you order CTS Installation, allow 1–2 extra days of processing time before the net ships – plan the install date accordingly.
Nets are custom cut on site, so order the width that clears the pool and enough length for the perimeter wrap. A net over an empty pool is a fall hazard – have the customer sign the Empty Pool, No Water Present – Acknowledgement if the pool will be drained.

Anchoring by Surface
A net only holds if its anchors hold. Where the anchor goes and what it bites into depends on the deck – and the closer anchors are to the pool edge, the tighter the spacing needs to be. Confirm the surface before drilling, and be ready to explain to the customer why “in the concrete deck” is the standard.
Concrete Deck (Preferred)
Installing in the concrete deck behind the coping is the preferred method for every net. It keeps tension off the coping so it can’t pull out, and it is the fastest, cleanest surface to core-drill.
- Brass keyhole anchors set with a ¾” core bit and tamping tool
- Anchors about 3” outside the coping, 18–24” apart
- Coping-only installs are the installer’s call – only if the coping can take the tension
Tile, Aggregate & Retaining Walls
Tile, exposed aggregate and raised walls each change how the anchor is set and how the net wears where it rolls over the edge. Surfaces the net crosses should be rounded (bullnose) and non-abrasive to protect the twine.
- Wall attachment kit or pad-eye anchors where the deck stops at a wall
- Extended cone head clips (2”, 4”, 6”) to reach over raised beams
- Surface-specific guides for tile, exposed aggregate and retaining walls
Pavers, Wood & Other Decks
Pavers, wood decks and softer surfaces can’t hold a brass keyhole anchor under tension. These installs use composite anchors, anchor pipe set into the base, or threaded wood-deck anchors – and should be confirmed with the office before quoting if you have not done one before.
- Composite anchors (Gray, Putty, Red, White) for pavers and softer decks
- Anchor pipe (18”) where a footing is needed
- Threaded wood-deck anchors for wood decks
Building a Net Order
Every All-Safe item is sold à la carte. There is no net kit and no package — you order each piece the job calls for, based on the pool, the deck surface and the tensioning layout.
Anchor kits bundle anchors with their matching clips, but a complete net is still built by selecting components individually.
What Every Net Install Needs
Net Material
Net material is the foundation of every installation. It ships as raw netting and is cut, fitted and wrapped on site.
Each order of net material includes:
- 5mm UV-stabilized polyethylene netting, 3½” squares
- Your choice of width: 12, 24, 34 or 50 ft
- Cut to the length you order
- Black, Blue or Tan
Perimeter Wrap: The finished edge is created on site with net perimeter wrap twine, sold by the cut length or by the spool in matching colors.
Anchors, Clips & Tensioning
(Ordered as Individual Components)
Anchoring and tensioning hardware is not sold as a single kit. A complete system requires:
Anchors
Brass keyhole, threaded brass, threaded wood-deck, composite, pad-eye or wall attachment – one per clip. Keyhole and Threaded Anchor Kits bundle anchors with clips.
Clips
- Cone head (1”–6”), round loop, pear loop, flat head or carabiner, matched to the anchor.
CTS Components
- Pulleys, pulley string and pull cord in the net color. Install the CTS yourself, or add “CTS Installation” (Single / Single Offset / Double / Double Offset) and All-Safe ties the pulleys in place before the net ships – extra fee, adds 1–2 days; offset placements need the custom CTS order form.
Tensioning Device
- Titan Tool small or large, Ratchet Assembly, or Round Loop Tool & Allen key. The homeowner keeps this tool.
Optional: Finishing & Storage
These pieces are optional. They are not part of a net order unless you add them, but they are what finishes a professional install and makes the net easy to live with day to day.
Each item includes what is needed to install that component on its own.
Optional Accessories & Add-Ons
None of the following come with net material or hardware. Add them to the order when the job calls for them:
- Installation tools — ¾” core bit, keyhole tamping tool, heat cutter and blades
- Labor and installation services, including CTS Installation if you would rather All-Safe tie the pulleys in place before the net ships
- Surface-specific anchors for pavers, wood, tile or wall installations
- Leaf cover, storage roller and storage bag
Nets are custom fitted on site, so qualify the pool, confirm the deck surface, and draw the layout with the customer before ordering.
Tools Checklist
Every net install uses the same short list of tools. Order these with your first net order if you don’t already have them:
- ¾” core bit — for brass keyhole anchors (how it’s used)
- Keyhole tamping tool — seats the anchor flush (how it’s used)
- Heat cutter and spare blades — cuts and seals the twine (how it’s used)
- A tensioning device for the job — Titan Tool, Ratchet Assembly, or Round Loop Tool & Allen Key Kit. This one stays with the homeowner, so order one per install.
- Rotary hammer or core drill with a water source for wet drilling — not sold by All-Safe
- Your own kit: tape measure, chalk, shop vac, utility knife, safety glasses
Browse everything in Net Installation Tools.
Install Day & Customer Handoff
A net is the one All-Safe product the homeowner operates every day, so the handoff matters as much as the install. Plan on 2–5 hours for a typical pool, plus another 1–2 hours for a spa depending on its size.
On site
- Chalk the anchor line for the install type and what the job needs, then core-drill and set the anchors
- Walk the net across, clip to the anchors, run the CTS and tension with the Titan Tool, ratchet or round loop tool
- Cut to shape, double-wrap the perimeter with twine and heat-seal the ends
- Secure the net & warning label with the install date and your company name
Demonstrate it before you leave. A proper walkthrough is the single best way to avoid a return trip. Have the homeowner take the net off and put it back on themselves while you are still there.
- Keep the water level up — the net needs the right water clearance beneath it to work
- Robotic and suction vacuums run under the net; skimming and brushing need the net off; chemicals go through the mesh with a funnel
- Leaves pass through 3½” squares — offer a leaf cover on top
- Store the net on a roller. Storage bags come in set sizes and are really meant for smaller spa nets, not full pool nets
- Inspect the net, twine and clips regularly — including for rodent damage — and check tension each season
- Ideally the net is not left over an empty pool. If the customer intends to, have them sign a waiver so the expectation is clear on both sides

Compatibility & Switching from Other Brands
All-Safe netting is heavier than most of what it replaces. Competing nets typically run 3.5–4mm twine; All-Safe is 5mm, so it is thicker and stronger, and it holds up better over the life of the install.
You also get more ways to anchor it. Brass keyhole anchors come in three sizes (0.730, 0.740 and 0.750), so existing anchor holes can often be reused when replacing another brand’s net. Beyond keyholes, All-Safe offers threaded brass, threaded wood-deck, composite, pad-eye and wall attachment anchors — so there is an option for surfaces where a standard brass keyhole will not hold.
Before ordering a replacement, confirm the anchor size, the clip style and the customer’s tensioning tool. Installers transitioning from another manufacturer are encouraged to send photos of the existing anchors and pulleys to All-Safe support for confirmation prior to purchase.
Ordering & Shipping
Order through the portal for fastest processing – Net Quick Order or the Shop. Your pricing shows on each product once you’re logged in. Orders can also be emailed to order@allsafepool.com with an order form, or called in to 800-786-8110.
- Orders ship from Orange, CA, Monday–Friday; most ship within 1–2 business days (allow 3–4 in peak season, April–July)
- Adding CTS Installation adds time. If you want All-Safe to tie the pulleys in place before the net ships, build that into your schedule — it is not a same-week turnaround
- UPS Ground is the default; USPS for small parts, freight for heavy or oversized orders, or free will-call pickup at our Orange office (Mon–Fri 8–4, closed 12–1). You choose at checkout
- The portal only sells what’s in stock – no backorders. If the width or length you need isn’t showing, it is likely out of stock. Orders can’t be changed or combined once placed; nets and leaf covers are not returnable
Safety & Compliance Notes
All-Safe Safety Nets are designed to meet applicable safety standards when installed correctly and in accordance with manufacturer guidelines and local regulations.
Installers are responsible for ensuring each installation complies with ASTM requirements, local building codes, and jurisdictional regulations applicable to the project site. Not every jurisdiction accepts a net as a pool barrier – check before quoting.
ASTM Compliance
There is no ASTM standard written specifically for safety nets. All-Safe nets are tested to ASTM F1346, the safety-cover standard, which most agencies apply to nets.
Compliance consists of two equally important parts — the product itself, and the way it is installed. Both have to be right.
Products Compliance
The materials of the All-Safe pool net have been tested to meet ASTM F1346-91 when installed following the guidelines of the standard:
- Supports weight (rated 485+ lbs over water)
- Prevents access to the water
- 3½” mesh blocks a 4” sphere
- UV-stabilized twine, marine-grade brass anchors, stainless clips
Installation Compliance
ASTM compliance is also dependent on proper installation:
- The pool qualifies – water clearance is maintained above the net
- Anchor spacing, placement and anchoring strength
- Full perimeter coverage including steps, benches and spas
- No 4” gap at edges, walls, ladders, slides or the tensioning point
- Net & warning label installed and visible
Installation compliance is determined by site conditions and installer execution, not the product alone.
Installer Responsibility
While All-Safe nets are ASTM-tested by design, final compliance depends on correct installation.
Installers must:
- Qualify the pool before quoting
- Select the right anchors for the surface
- Follow ASTM guidelines and manufacturer instructions
- Verify local code requirements and whether a net is accepted as a barrier
The end user is responsible for maintaining the net, keeping the pool at proper water level, and calling you for service when anything looks worn.
